A special event is said to have taken place at the Chindli Chapel in Gersau. A father rowed with his child from the inn to the Treib in the direction of Gersau. The child was hungry and begged for bread, over and over again. The father promised that he would give him bread as soon as they reached land. But he didn't keep his promise, instead he grabbed the child by the feet and smashed its head so hard against a rock that it died. He threw the body into the lake. The only thing that was later found of the child was a bloody shoe, which washed ashore not far from Gersau. Hence the name "Rotschuo". The murderer went to war as a mercenary. One evening, in a drunken stupor, he told of his crime. He was arrested, extradited back home and sentenced to death.
